As commented in the link provided and also on the magento forums but this appears to be an issue with port 4430 not being open on your server.
It also appears to be part of the extension called PaymentSense. If you are using this extension then I would suggest that you have a look into this port, either you can sort this yourself or contact your hosting provider for help with this.
